Kanotix is supposed to detect h/w like sound cards and appropriately configure it or driver if I'm not mistaken. Mint does this and I have no problem playing the Gnome Media Player. However I've failed to get any sound out of it here.

Have followed this, but still problem persists. I tend to think it's something to do with thiis error:
ALSA lib pcm_dmix.c:1018:(snd_pcm_dmix_open) unable to open slave
play FAIL formats: can't open output file `default': snd_pcm_open error: Device or resource busy
Something seems to be either blocking access to or hogging the sound card. Kaffeine upon start-up comes up with the following:
Sorry - Kaffeine
Cannot create audio output
before crashing.

Thanks for the link and its related links which I am now having to wade through while waiting on more suggestions.

If some application blocks your sound device, you can see that via

Code:

lsof | grep snd

If some apps that should be closed still block your device, try to kill them (killall or kill).

Flash Plugin seems to always grab the sound device file, but this time appears to have relinquished it to the active process. It is this same plugin plugin-co which had the sound device file before, when nothing was happening. So it remains a puzzle as to why this plugin now seems to be behaving properly.

Attached file lists all processes on m/c., and maybe s.o. can spot one which could have been responsible for locking out processes from the sound device file.
